2.4 network down but 5 is up...Comcast's fault or problem with the router or interference?

Mermaid 2,179 910 October 19, 2015 at 06:37 PM
I'm curious...we just had Comcrap Internet and phone installed last week at my business. Internet and phones went down today in our area Mad and are back up now, several hours later, but I am having a weird problem that I haven't experienced before and would like to know if it's a problem here in my shop or possibly still with Comcrap.

Desktop is connected via ethernet cable to modem and speed is 30/12 (on a 25/5 plan). So no problem there.

Our cell phones are connected via Comcrap's modem/router to the 5 ghz network...also excellent at 30/13.

Laptop and switching the cell phones to the 2.4 ghz network...pretty much nothing. 1 to 5, which is essentially death.

Could this be a Comcast problem (as they weren't supposed to be done with the outage for another hour or so) or can it only be a problem with either the modem/router itself OR a problem with something in the bakery interfering with the wireless signal (although we are running no microwaves or any equipment other than a gas oven right now)?

Thanks for any insight someone can give me. hug

2.4ghz = lots of possible interference in that band..... MW's and some landline phones...

I'd watch it over time and if it comes and goes, I'd say it's interference (even with other AP's) and just write it off.

try unplugging your routerd and modem




if your paying for comcat router modem call its tech support

turn off other comcat cutomers using your router

I would start by rebooting the comcast equipment. I would then use an app on the laptop like issider or on your phone like wifi scanner to see the other accesspoints in the area on 2.4ghz to see if your channel was crowded and needed to be moved. I would then call your provider since your using their equipment. Most often providers equipment is not the best.

If you have an iPhone, I use Wifi Sweetspot to test for dead spots in my house.

Most devices should be on 2.4 There are pros and cons to using 2.4 and 5 GHZ. As mentioned above, 2.4 is prone to some interference from cordless phones, microwaves, etc. However, 2.4 penetrates walls a whole lot better than 5. The faster 5 GHZ will get you better local speeds (not necessarily faster internet) but does not penetrate structures nearly as well as 2.4. In my house (a 2 story 2050 sq ft townhouse), I cannot use 5 GHZ except for in the 3 rooms surrounding the router. Only 2.4 goes upstairs. We will be moving into a 1 story house in a few weeks that has a more open floor plan. So, I'm hoping 5 GHZ will work better there.

I once prayed to God for a bike, but quickly found out he didnt work that way...so I stole a bike and prayed for his forgiveness. Angel Not

I believe it is with your wifi router or some interference. A lot of gadgets nowadays run on 2.4ghz so they could cause interference.
